Using Remote Data Objects and the RemoteData Control

This chapter provides an overview of the features of the Remote Data Objects (RDO) programming model and the RemoteData control. The information in this chapter can help you make a decision regarding which data access programming model to use in your client/server application.

Remote Data Objects implement a set of objects to deal with the special requirements of remote data access. RDO implements a thin code layer over the ODBC API and driver manager that establishes connections, creates result sets and cursors, and executes complex procedures using minimal workstation resources. Although RDO is also accessed by DAO when your code creates an ODBCDirect Workspace object, documentation for this implementation can be found by searching for specific ODBCDirect topics.

Note RDO and the RemoteData control are designed to be used only in 32-bit operating systems such as Microsoft Windows 95 (or later) or Microsoft Windows NT.
